1、添加相关的依赖,spring-boot-starter-data-jpa在 IEDA中创建SpringBoot2.0项目-超详细(一)博客中已经添加,只需添加以下依赖即可:
org.springframework.boot
spring-boot-starter-thymeleaf
net.sourceforge.nekohtml
nekohtml
1.9.22
org.apache.shiro
shiro-spring
1.4.0
2、在application.properties文件中添加:
#shiro相关
spring.jpa.database=mysql
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=update
spring.jpa.ddl-auto=update
spring.jpa.naming.strategy=org.hibernate.cfg.DefaultComponentSafeNamingStrategy
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5Dialect
spring.thymeleaf.cache=false
spring.thymeleaf.mode=LEGACYHTML5
如果是yml文件添加:
spring:
jpa:
database: mysql
show-sql: true
hibernate:
ddl-auto: update
naming:
strategy: org.hibernate.cfg.DefaultComponentSafeNamingStrategy
properties:
hibernate:
dialect: org.hibernate.dialect.MySQL5Dialect
thymeleaf:
cache: false
mode: LEGACYHTML5
3、添加相关的实体类:
用户信息UserInfo:
@Data
@ToString
@Entity
public class UserInfo implements Serializable {
@Id
@GeneratedValue
private Integer uid;
@Column(unique = true)
private String username;//帐号
private String name;//名称(昵称或者真实姓名,不同系统不同定义)
private String password; //密码;
private String salt;//加密密码的盐
private byte state;//用户状态,0:创建未认证(比如没有激活,没有输入验证码等等)--等待验证的用户 , 1:正常状态,2:用户被锁定.
@ManyToMany(fetch = FetchType.EAGER)//立即从数据库中进行加载数据;
@JoinTable(name = "SysUserRole", joinColumns = {@JoinColumn(name = "uid")}, inverseJoinColumns = {@JoinColumn(name = "roleId")})
private List roleList;// 一个用户具有多个角色
}
角色信息SysRole:
@Entity
public class SysRole implements Serializable {
@Id
@GeneratedValue
private Integer id; // 编号
private String role; // 角色标识程序中判断使用,如"admin",这个是唯一的:
private String description; // 角色描述,UI界面显示使用
private Boolean available = Boolean.FALSE; // 是否可用,如果不可用将不会添加给用户
//角色 -- 权限关系:多对多关系;
@ManyToMany(fetch = FetchType.EAGER)
@JoinTable(name = "SysRolePermission", joinColumns = {@JoinColumn(name = "roleId")}, inverseJoinColumns = {@JoinColumn(name = "permissionId")})
private List permissions;
// 用户 - 角色关系定义;
@ManyToMany
@JoinTable(name = "SysUserRole", joinColumns = {@JoinColumn(name = "roleId")}, inverseJoinColumns = {@JoinColumn(name = "uid")})
private List userInfos;// 一个角色对应多个用户
//此处是set和get方法,可以利用编译器去自动生成
}
权限信息SysPermission:
@Entity
public class SysPermission implements Serializable {
@Id
@GeneratedValue
private Integer id;//主键.
private String name;//名称.
@Column(columnDefinition = "enum('menu','button')")
private String resourceType;//资源类型,[menu|button]
private String url;//资源路径.
private String permission; //权限字符串,menu例子:role:*,button例子:role:create,role:update,role:delete,role:view
private Long parentId; //父编号
private String parentIds; //父编号列表
private Boolean available = Boolean.FALSE;
@ManyToMany
@JoinTable(name = "SysRolePermission", joinColumns = {@JoinColumn(name = "permissionId")}, inverseJoinColumns = {@JoinColumn(name = "roleId")})
private List roles;
//此处是set和get方法,可以利用编译器去自动生成
}
此处有个问题,就是只有UserInfo类可以使用lombok表达式,其他两个类不能使用,只能自己手动去生成set/get方法,此处报了以下错误,博主搞了半天一直报以下错误:
org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role: com.xhy.xczx.pojo.SysRole.userInfos, could not initialize proxy - no Session
由于能力有限没能解决,有解决的可以指正,所以这两个实体类未能使用lombok表达式,只能手动写的set/get方法,然后启动下项目,无报错信息后即可在数据库中自动生成对应的几张表:
然后插入需要的数据:
INSERT INTO `user_info` (`uid`,`username`,`name`,`password`,`salt`,`state`) VALUES ('1', 'admin', '管理员', 'd3c59d25033dbf980d29554025c23a75', '8d78869f470951332959580424d4bf4f', 0);
INSERT INTO `sys_permission` (`id`,`available`,`name`,`parent_id`,`parent_ids`,`permission`,`resource_type`,`url`) VALUES (1,0,'用户管理',0,'0/','userInfo:view','menu','userInfo/userList');
INSERT INTO `sys_permission` (`id`,`available`,`name`,`parent_id`,`parent_ids`,`permission`,`resource_type`,`url`) VALUES (2,0,'用户添加',1,'0/1','userInfo:add','button','userInfo/userAdd');
INSERT INTO `sys_permission` (`id`,`available`,`name`,`parent_id`,`parent_ids`,`permission`,`resource_type`,`url`) VALUES (3,0,'用户删除',1,'0/1','userInfo:del','button','userInfo/userDel');
INSERT INTO `sys_role` (`id`,`available`,`description`,`role`) VALUES (1,0,'管理员','admin');
INSERT INTO `sys_role` (`id`,`available`,`description`,`role`) VALUES (2,0,'VIP会员','vip');
INSERT INTO `sys_role` (`id`,`available`,`description`,`role`) VALUES (3,1,'test','test');
INSERT INTO `sys_role_permission` VALUES ('1', '1');
INSERT INTO `sys_role_permission` (`permission_id`,`role_id`) VALUES (1,1);
INSERT INTO `sys_role_permission` (`permission_id`,`role_id`) VALUES (2,1);
INSERT INTO `sys_role_permission` (`permission_id`,`role_id`) VALUES (3,2);
INSERT INTO `sys_user_role` (`role_id`,`uid`) VALUES (1,1);
然后在resources/templates下创建以下html文件:
为了避免命名上的问题,特意贴出各个页面名字:
403.html
index.html
login.html
userInfo.html
userInfoAdd.html
userInfoDel.html
以下只有login.html页面有具体内容,fkHtml.ftl属于以前Freemarker教程中的页面,不用新增,其他页面根据自己需求去写:
login.html:
Login
错误信息:
现在贴出Shiro的两个核心类:
ShiroConfig.java:
package com.xhy.xczx.shiro;
import org.apache.shiro.authc.credential.HashedCredentialsMatcher;
import org.apache.shiro.mgt.SecurityManager;

@Configuration
public class ShiroConfig {
@Bean
public ShiroFilterFactoryBean shirFilter(SecurityManager securityManager) {
System.out.println("ShiroConfiguration.shirFilter()");
ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
shiroFilterFactoryBean.setSecurityManager(securityManager);
//拦截器.
Map filterChainDefinitionMap = new LinkedHashMap();
// 配置不会被拦截的链接 顺序判断
filterChainDefinitionMap.put("/static/**", "anon");
//配置退出 过滤器,其中的具体的退出代码Shiro已经替我们实现了
filterChainDefinitionMap.put("/logout", "logout");
//:这是一个坑呢,一不小心代码就不好使了;
//
filterChainDefinitionMap.put("/**", "authc");
// 如果不设置默认会自动寻找Web工程根目录下的"/login.jsp"页面
shiroFilterFactoryBean.setLoginUrl("/login");
// 登录成功后要跳转的链接
shiroFilterFactoryBean.setSuccessUrl("/index");
//未授权界面;
shiroFilterFactoryBean.setUnauthorizedUrl("/403");
shiroFilterFactoryBean.setFilterChainDefinitionMap(filterChainDefinitionMap);
return shiroFilterFactoryBean;
}
/**

*/
@Bean
public HashedCredentialsMatcher hashedCredentialsMatcher(){
HashedCredentialsMatcher hashedCredentialsMatcher = new HashedCredentialsMatcher();
hashedCredentialsMatcher.setHashAlgorithmName("md5");//散列算法:这里使用MD5算法;
hashedCredentialsMatcher.setHashIterations(2);//散列的次数,比如散列两次,相当于 md5(md5(""));
return hashedCredentialsMatcher;
}
@Bean
public MyShiroRealm myShiroRealm(){
MyShiroRealm myShiroRealm = new MyShiroRealm();
myShiroRealm.setCredentialsMatcher(hashedCredentialsMatcher());
return myShiroRealm;
}
@Bean
public SecurityManager securityManager(){
DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
securityManager.setRealm(myShiroRealm());
return securityManager;
}
/**

*/
@Bean
public AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor(SecurityManager securityManager){
AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor = new AuthorizationAttributeSourceAdvisor();
authorizationAttributeSourceAdvisor.setSecurityManager(securityManager);
return authorizationAttributeSourceAdvisor;
}
@Bean(name="simpleMappingExceptionResolver")
public SimpleMappingExceptionResolver
createSimpleMappingExceptionResolver() {
SimpleMappingExceptionResolver r = new SimpleMappingExceptionResolver();
Properties mappings = new Properties();
mappings.setProperty("DatabaseException", "databaseError");//数据库异常处理
mappings.setProperty("UnauthorizedException","403");
r.setExceptionMappings(mappings); // None by default
r.setDefaultErrorView("error"); // No default
r.setExceptionAttribute("ex"); // Default is "exception"
//r.setWarnLogCategory("example.MvcLogger"); // No default
return r;
}
}
MyShiroRealm.java:
package com.xhy.xczx.shiro;
import com.xhy.xczx.pojo.SysPermission;
import com.xhy.xczx.pojo.SysRole;
import com.xhy.xczx.pojo.UserInfo;
import com.xhy.xczx.service.UserInfoService;
import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.AuthenticationInfo;
import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.authc.SimpleAuthenticationInfo;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.authz.SimpleAuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;
import org.apache.shiro.util.ByteSource;
import javax.annotation.Resource;
public class MyShiroRealm extends AuthorizingRealm {
@Resource
private UserInfoService userInfoService;
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
System.out.println("权限配置-->MyShiroRealm.doGetAuthorizationInfo()");
SimpleAuthorizationInfo authorizationInfo = new SimpleAuthorizationInfo();
UserInfo userInfo = (UserInfo)principals.getPrimaryPrincipal();
for(SysRole role:userInfo.getRoleList()){
authorizationInfo.addRole(role.getRole());
for(SysPermission p:role.getPermissions()){
authorizationInfo.addStringPermission(p.getPermission());
}
}
return authorizationInfo;
}
/*主要是用来进行身份认证的,也就是说验证用户输入的账号和密码是否正确。*/
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token)
throws AuthenticationException {
System.out.println("MyShiroRealm.doGetAuthenticationInfo()");
//获取用户的输入的账号.
String username = (String)token.getPrincipal();
System.out.println(token.getCredentials());
//通过username从数据库中查找 User对象,如果找到,没找到.
//实际项目中,这里可以根据实际情况做缓存,如果不做,Shiro自己也是有时间间隔机制,2分钟内不会重复执行该方法
UserInfo userInfo = userInfoService.findByUsername(username);
System.out.println("----->>userInfo="+userInfo);
if(userInfo == null){
return null;
}
SimpleAuthenticationInfo authenticationInfo = new SimpleAuthenticationInfo(
userInfo, //用户名
userInfo.getPassword(), //密码
ByteSource.Util.bytes(userInfo.getCredentialsSalt()),//salt=username+salt
getName() //realm name
);
return authenticationInfo;
}
}
然后编写dao、service和Controller中内容:
UserInfoDao:
public interface UserInfoDao extends CrudRepository {
UserInfo findByUsername(String username);
}
UserInfoService:
public interface UserInfoService {
/**通过username查找用户信息;*/
UserInfo findByUsername(String username);
}
UserInfoServiceImpl:
@Service
public class UserInfoServiceImpl implements UserInfoService {
@Resource
private UserInfoDao userInfoDao;
@Override
public UserInfo findByUsername(String username) {
System.out.println("UserInfoServiceImpl.findByUsername()");
return userInfoDao.findByUsername(username);
}
}
UserInfoController:
@Controller
@RequestMapping("/userInfo")
public class UserInfoController {
/**
* 用户查询.
* @return
*/
@RequestMapping("/userList")
@RequiresPermissions("userInfo:view")//权限管理;
public String userInfo(){
return "userInfo";
}
/**
* 用户添加;
* @return
*/
@RequestMapping("/userAdd")
@RequiresPermissions("userInfo:add")//权限管理;
public String userInfoAdd(){
return "userInfoAdd";
}
/**
* 用户删除;
* @return
*/
@RequestMapping("/userDel")
@RequiresPermissions("userInfo:del")//权限管理;
public String userDel(){
return "userInfoDel";
}
}
核心跳转类HomeController:
@Controller
public class HomeController {
@RequestMapping({"/","/index"})
public String index(){
return"/index";
}
@RequestMapping("/login")
public String login(HttpServletRequest request, Map map) throws Exception{
System.out.println("HomeController.login()");
// 登录失败从request中获取shiro处理的异常信息。
// shiroLoginFailure:就是shiro异常类的全类名.
String exception = (String) request.getAttribute("shiroLoginFailure");
System.out.println("exception=" + exception);
String msg = "";
if (exception != null) {
if (UnknownAccountException.class.getName().equals(exception)) {
System.out.println("UnknownAccountException -- > 账号不存在:");
msg = "UnknownAccountException -- > 账号不存在:";
} else if (IncorrectCredentialsException.class.getName().equals(exception)) {
System.out.println("IncorrectCredentialsException -- > 密码不正确:");
msg = "IncorrectCredentialsException -- > 密码不正确:";
} else if ("kaptchaValidateFailed".equals(exception)) {
System.out.println("kaptchaValidateFailed -- > 验证码错误");
msg = "kaptchaValidateFailed -- > 验证码错误";
} else {
msg = "else >> "+exception;
System.out.println("else -- >" + exception);
}
}
map.put("msg", msg);
// 此方法不处理登录成功,由shiro进行处理
return "/login";
}
@RequestMapping("/403")
public String unauthorizedRole(){
System.out.println("------没有权限-------");
return "403";
}
}
最后进行测试:
1、编写好后就可以启动程序,访问http://localhost:8081
页面进入首页,由于没有登录就会跳转到http://localhost:8081/login
页面。登录之后就会跳转到index页面,登录后,直接在浏览器中输入http://localhost:8081/userInfo/userList
访问就会看到用户信息。http://localhost:8081/logout
页面,退出登录,上面这些操作时候触发MyShiroRealm.doGetAuthenticationInfo()这个方法,也就是登录认证的方法。
2、登录admin账户,访问:http://127.0.0.1:8081/userInfo/userAdd
显示用户添加界面,访问http://127.0.0.1:8081/userInfo/userDel
显示403没有权限。上面这些操作时候触发MyShiroRealm.doGetAuthorizationInfo()这个方面,也就是权限校验的方法。
3、修改admin不同的权限进行测试。
测试结果如下:
隐含内容:自动生成数据库表结构
在配置文件里配置下面内容,在数据库中创建数据库,启动项目可以自动生成对应的表和表结构。
spring.jpa.hibernate.ddl-auto=update
spring.jpa.hibernate.dialect=org.hibernate.dialect.MySQL5Dialect
